A kind of composition containing ZJ10520 and ryanodine receptor insecticides
Technical field
The invention belongs to pesticide field, is related to a kind of Fungicidal insecticidal composition for being used to prevent and treat agricultural disease.
Background technology
In agricultural production process, fungal disease and insect are the principal elements for influenceing yield and quality.To improve farming
The yield and quality of thing, the agricultural chemicals of preventing and treating pest and disease damage need to be used, such as insecticide and bactericide.
Conventional insecticide such as four chlorantraniliproles, chlorine fluorine cyanogen insect amide, Rynaxypyr and bromine cyanogen insect amide etc., performance
It is as follows:
Four chlorantraniliproles, chemical name:The bromo- N- of 3- [2,4- bis- chloro- 6- (methyl-carbamoyl) phenyl] -1- (3,5- bis-
Chloro-2-pyridyl) -1H- pyrazoles -5- formamides, it is a kind of bisamide insecticides, it is excellent to lepidoptera pest preventive effect;
Chlorine fluorine cyanogen insect amide, chemical name:The chloro- N1- of 3- (2- methyl -4- sevoflurane isopropyls base)-N2- (1- methyl isophthalic acids -
Cyano ethyl) phthalic amide, it acts on insect ryanodine receptor, promotes the endogenous calcium ion release of insect cell, influences
Contraction of muscle, and then cause insect death;
Rynaxypyr (Chlorantraniliprole), chemical name:The bromo- N- of 3- [4- chloro-2-methyl -6- [(first
Carbamoyl) benzene] -1- (3- chloropyridine -2- bases) -1H- pyrazoles -5- formamides are a kind of Novel ortho formamido benzoyls
Amine insecticide, the ryanodine receptor that it can be in efficient activation insect bodies, the calcium ion in intracellular calcium store is excessively discharged, is caused
Insect paralysis is dead, and various lepidopterous insects are shown with excellent prevention effect;
